In southern New South Wales an emergency warning has been issued for residents on Timber Top Road near Bungendore.

The NSW Rural Fire Service (RFS) says the fire is burning out-of-control in the Sand Hills area 13 kilometres east of Bungendore.

People on nearby rural properties are being urged to remain alert and the Kings Highway has been temporarily closed in both directions between Bungendore and Braidwood.

Palerang mayor Pete Harrison says the forecast for strong winds and high temperatures could have caused more serious problems.

"We had a couple of small fires which were brought under control relatively quickly earlier in the day, and another fire now which is active out along the Kings Highway," he said.

"But I'm led to understand while the fire is not under control, its not a major concern at this stage."

The Dean's Gap fire in the Shoalhaven region of NSW has also closed main road 92 between Braidwood and Nowra.

ACT fire crews have already put out fires at Hallet Place and Marconi Crescent in Kambah, as well as Coppins Crossing Road in Belconnen, Baldwin Drive in Kaleen and in Oaks Estate on the ACT-New South Wales border.

Crews also extinguished a grassfire in the backyard of a home at Betts Place in Higgins caused by tree branches touching overhead power-lines.

Fires at Macquarie Oval, Mirrabei Drive in Ngunnawal, Anketell Street in Greenway and Darwinia Terrace in Chapman have also been extinguished.
